Target is apologizing for describing the color of a plus-size dress as ''manatee gray.'' The label for the same color dress in smaller sizes says "dark heather gray."

Susan Clemens, a self-described “plus-size” woman from California, told ABC News she was taken aback when she saw a friend’s Facebook post with a picture of a plus-size Target maxi dress described as “manatee gray.”

When Clemens went on the Target.com site herself to see if her friend’s post was true, she discovered not only that the plus-size style was described as “manatee gray,” but the regular size of the exact same maxi dress was described as “dark heather gray.”

Clemens took to Twitter to express her outrage, posting a screen shot of the two identical dresses with the different descriptors along with her tweet.
